What's in the zip

tsx-reader-export-1.0.0-windows-x64\
  tsx-reader-export-viewer\
    tsx-reader-export-viewer.exe     <- the GUI: double-click this
    ...                     <- app files (keep the folder together)
  tsx-reader-export.exe              <- the command line converter
  node_modules\             <- required by tsx-reader-export.exe (keep together)
  cursor-canvas.compat.mjs
  run-cli.bat
  README.txt

The viewer (GUI)

Double-click tsx-reader-export-viewer\tsx-reader-export-viewer.exe.

Action	How
Open a canvas	Open .tsx button, or drag-and-drop a .tsx onto the window
Preview	rendered live in the window
Save the result	Save as HTML — writes a self-contained .html
Print / export PDF	Print / PDF — opens the Windows print dialog; choose Microsoft Print to PDF or Save as PDF

Starts in about 0.2 seconds (the app folder is shipped unpacked on purpose —
a single-file "portable" build re-extracts ~200 MB on every launch and took 23s).

The CLI

tsx-reader-export.exe my.canvas.tsx out.html
tsx-reader-export.exe my.canvas.tsx out.html --title "My Page"
tsx-reader-export.exe my.canvas.tsx out.html --color-scheme dark
tsx-reader-export.exe --help

node_modules\ must stay next to tsx-reader-export.exe — the executable embeds the
Node runtime but loads React and the cursor/canvas shim from that folder.

Prefer a visible console? Use run-cli.bat.

What you get

The output is a single self-contained .html file — all CSS is inlined, with
no external stylesheet links, so it opens offline and can be emailed or archived
as one file. It is fully rendered; it does not need React in the browser.

Verify the download works

Both programs write a detailed log if anything goes wrong:

Program	Log location
tsx-reader-export.exe	logs\tsx-reader-export.log next to it (or %TEMP%)
viewer	%APPDATA%\tsx-reader-export-viewer\viewer.log

Headless self-check of the packaged viewer:

"tsx-reader-export-viewer\tsx-reader-export-viewer.exe" --smoke path\to\canvas.tsx

Known issues

• SmartScreen warning. The binaries are unsigned. Choose
  More info → Run anyway. To avoid it entirely, right-click the .exe →
  Properties → tick Unblock.
• Antivirus false positives. Unsigned self-contained executables are
  sometimes flagged. The viewer is an unpacked folder, so you can also run
  tsx-reader-export-viewer.exe from win-unpacked-style layout without a wrapper.
• macOS and Linux builds are not included in this release.

Requirements

• Windows 10 or later, 64-bit.
• No Node.js, no Python, no build tools.
